To all whom it may concern) I j I Be it known that I, CHARLES CooKMAN ToMnrN-soN, a citizen of the United States,

and a resident of Plainfield, county of Union,

Further objects of the invention will ap- I pear'in thespecific'ation out in the claims. In the drawings, Figure 1 is a top plan view of a section of sheet-piling embodying my in vention. Fig. 2 is a partial front elevation of the'same. Fig. 3 is a view similar to that 'of F 1, showing a modified construction of the piles.

Referring to Figs. 1 and 2 of the drawings, each pile consists of a trough-shaped beam 1, shown as a channel-beam of standard section having a'web 11 and flanges 12. Secured behind the rear'face of the web 11 andin vertical alinement therewith at its middle point is a second channelebeam 2, having a relatively narrow web 21 parallel with the web 1 1 of the beam 1 and having lateral flanges 22 projecting toward the beam 1. The beams land 2 are secured together by a bolt 3 and nut 31, a sleeve 4 being slipped over the bolt 3 to space the beams 1 and 2 a proper distance apart. As will be clearly seen in Fig. 1 of the drawings, this distance is such as to receive the lateral flange 12 of the channel-beam 1 of the adjacent pile, so that the flange 12 is received in a recess formed of a portion of the web 11 of the channel-bar 1, the flange 22 of the channel-b ar 2, and the sleeve 4, which forms a spacing means between the two spacing-b ars. As each flange 12 is interlocked in a similar way, it will be seen that the pile ractically consists of a double thickness of t e web 11 of the bars 1, the rigidity of which is increased by the flanges 22. It will be seen in Fig. 2 that the bolts 3 are disposed at convenient distances in a vertical line, so that the piles are very rigid and very solidly interlocked.

Fig. 3 shows a modified form of the device I Specification of Letters Patent. Application. filed November 18,1905. Serial No. 287.938.

which is advantageous where a somewhat cheaper and less rigid sheet-piling is required. In this case the channelbar 1 is pierced for the reception of two vertical lines of bolts 3, each line being at a short distance from the edge'of the web -11. Each bolt 3 is as before surrounded by a sleeve 4 and, acts in connec tion with the nut 31 to secure behind the rear face of the web 11 of the beam 1 a second beam 2. The interlocking of the flanges 12 of the adjacent beamsin the recess f or'med as before by a portionof the web 11 of the large beam 1, the flange 22 ofthe smaller beam 2, and the spacing-sleeve 4 will be readily understood from an inspection of the drawings. It will be seen that the beams 2 are as before'channeLbeams; but it is obvi ous that one of the'lateral flanges22 of each of these beams hasno function and might be dispensed with.

fer to use the small channel-beam because it' In practice, however, I pre is a rolled section of standard pattern and can be easily procured in market, besides'having a practically unimpaired value when the pile is pulled up. It 'will, jbe seen that in both cases the webs 11 ofthe main channel-bars 1 are securely held together back to back, so as' to form a very'rigid sheet and so as to uickly rust together if a tight sheet-piling, as or coffer-dam work, is required. 3

By the term rear face as applied to a trough-shaped or channel beam I of course refer to that side of the web opposite to that from which the flanges project.

In a-copending application of even date herewith, filed November 18,1905, Serial No. 287,939, I have shownand claimed interlocking piles composed of beams spaced apart by timber or wood fillers or the like. It is clear that I do not herein claim any of the specific features shown and claimed in that application. a variety of corner-piles and a form of shoe adapted to be secured to the lower end of each pile. It will be seen that the piles of the present application may be locked together at any desired angle by any of the means shown in that application or by any well-known means and that any convenient shoe may be applied to the foot of each of the piles of the present case. It is also clear that modifications other than those shown may be made in the form of the device without departing from the spirit of the invention.

The advantages of my invention are the simplicity of construction of the piles, owing In that application I have also shown to the fact that they are made of standaid rolled sections which can be purchased in open market, the ease with which they may be driven in their interlocked position, and the practically complete salvage which results when the piles are withdrawn by reason of the fact that the taking out of the bolts-3 leaves the metal beams in practicallyas useful condition as before the piles were driven.

What I claim is 1. An interlocking pile comprising a troughshaped beam, a second beam having a flange secured at the rear face of said trough-beam with its flange projecting theretoward, and spacing means between said beams, whereby a recess is formed between the web of the trough-beam, the flange of the second beam and the spacing means for the reception of the flange of a second trough-beam to be interlocked therewith.

2. An interlocking pile comprising a troughshaped beam, a second trough-shaped beam having a relatively narrow web secured at the rear face of said first-named beam with its lateral flange projecting theretoward, and means interposed between said beams, whereby a recessis formed bythe webvof the first-named beam, the flange of the secondnamed beam and the spacing means for the reception of a flange of the trough-shaped beam of an adjacent pile to be interlocked therewith. v

v3. An interlocking pile comprisingatroughshaped beam, a beam'having a flange, a bolt for securing said second-named beam at the rear face of said first-named beam, and a sleeve on said bolt for spacing said beams apart, said second-named beam having its flange projecting toward the rear face of said first-named beam and'forming therewith and with said sleeve a recess iforthe reception of the flange of a second trough-shaped beam to be interlocked therewith.

4. An interlocking pile comprising a troughshaped beam, two beams of relatively narrow web, each having a flange and each secured at the rear face of said first-named beam adjacent the edge of its web with said flange projecting theretoward, and spacing means between said first-named beam and each of said second-named beams, whereby a recess is formed adjacent each edge of said firstnamed beam between the web thereof, the flange of one of said second-named beams and the spacing means for the rece tion of the flange of a second trough-shape beam to be interlocked therewith.

5. Sheet-piling comprising a pluralityof similar interlocking piles, reach comprising a trough-shaped beam, a second beam havin a .flangeand secured to the rear face of sair trough-shaped beam with its flange projecting theretoward, and spacing means between said beams, whereby a recess is formed by the web of the trough-shaped beam, the flange of the second-named beam and the spacing means for the reception-of the flange of1 the trough-shaped beam of the adjacent pi e.

6. Sheet-piling composed ofa :plurality of similar interlocking piles, each comprisinga trough-shaped beam, two beams ofrelativoly narrow web, each having a flange and each secured at the rearface of said trough-shaped beam adjacent the edge of its web with said flange projecting theretoward, and spacing means between said first-named beam and each of said second-named beams, whereby a recess is formed adjacent the edge of said first-named beam between the web thereof, the flange on one of said second-named beams and one ofthe spacing means for the reception of the flangeof the trough-shaped beam of theadjacentpile.

In testimony whereof I have signed this specification in the presenceof =tWo subscribing witnesses.
